Here Bankers will collect the customer finger prints and mobile number while opening the accounts then customer can access the ATM machine. When the customer enters ATM and after inserting card he must place finger on the finger print module then he get automatically generated 4-digit code every time as a message to the mobile of the authorized customer through GSM modem connected to the microcontroller. The code received by the customer should be entered by pressing the keys on the touch screen, after only that he will be able for further transaction. This proposal will go a long way to solve the problem of account safety. Keywords Fingerprint, ATM, GSM modem, Magnetic strip card I. INTRODUCTION In today s fast life no one wants to stand in long queues for banking operation, they don t want to wait for too long time thus many of us are using ATM machine. Fast development of banking technology has various advantages and disadvantages to banking activities and transactions are the advent of automated teller machine (ATM)[3]. ATMs are electronic banking machines located in different places and the customers can make basic transactions without the help of bank staffs. With the help of ATM the user can perform several banking activities like money transfer, cash withdrawal, credit card payment, paying various home usage bills like electricity, and phone bill [4]. Rapid development of banking technology has changed the way banking activities are dealt with. One banking technology that has impacted positively and negatively to banking activities and transactions is the advent of automated teller machine (ATM). It is a computerized machine designed to dispense cash to bank customers without need of human interaction. Today the ATM users are increase in numbers. They use the ATM cards for banking transactions like deposits, transfers, balance enquiry, mini statement, withdrawal, fast cash, etc. The ATM machine has card Reader and keys as input devices and display screen, cash dispenser, receipt printer, speaker as output devices. ATMs are connecting to a host processor, which is a common gateway through which various ATM networks become available to users. Various banks, independent service providers owned this host processor [1].Account information of user is stored on the magnetic strip present at the back side of the ATM card. When we enter the card in the card reader, the card reader captures the account Information and the information is used for the transaction purpose. And we have to insert the pin by keys. The pin is the 4 digit number given to all ATM card holders. ATM card holders pin are different from each others. The number is verifying by the bank and allows the customers to access their account. The password is only identity so anyone can access the account when they have the card and correct password. Once the card and the password is stolen by the culprit they can take more money from the account in shortest period, it may bring huge financial losses to the users [2]. 2014, IJCSMC All Rights Reserved 28

2 In this paper we discuss some biometric uses to prevent the fraud at the time of ATM transaction a biometric measure as a means of enhancing the security for banking system for both customers & bankers also. Biometric authentication can be further divided into some different biometric options i.e. Fingerprint scanning, Face recognition, Iris scanning etc. But here we are introducing new technology which works the technology fingerprint recognition system and nominee for the main user and GSM technology. Biometric technology provides strong and indisputable authentication. Because biometrics data are unique, cannot be shared, cannot be copied and cannot be lost. The fingerprint based identification is one of the most mature and proven technique [6]. So we use the fingerprint for the identification purpose. Physical characteristics include fingerprint, hand or palm geometry, retina, iris and face while popular behavioral characteristics are signature and voice. Biometrics technologies are a secure means of authentication The fingerprint of the card and nominee will be stored in the db of the bank when the cardholder or the nominee tries to access the account; they will have to enter the pin and need to enroll the fingerprint. The finger print is check by the bankers, if it is in the data base the 4 digit code is send to the user by the GSM technology (Global system for mobile communication)[5]. The GSM technology is cellular network which means that mobile phone connect to it by searching for cells in the immediate vicinity. The GSM modem connected to the microcontroller generates the 4 digit code to the main user mobile number. The user can access the account after he/she enter one time password, after they can begin the transactions. We made the transactions what we want like deposits or withdrawal, etc. After complete our transaction we can get the card.this helps to reduce the chances of fraud occurring in ATM usage [7]. II. RELATED WORKS ATM can be described as Any Time Money. We can get money at anytime anywhere only through ATM machines. To do the secure transactions we need biometric authentication. Biometric authentication is a growing and controversial field. Today biometric laws and regulations are in process and biometric industry standards are being tested. Automatic recognition based on who you are as opposed to what you know (pin) or what you have (ID card). A. Discussion Implementation of the security by using fingerprint recognition and GSM, by Pennam Krishna murthy & Maddhusudhan reddy using fingerprint recognition method, remote authentication, message alarming and Gobar and direction filter algorithm, it is more safe and reliable and easy to use but it is slow when dealing with high capacity requirements. The United Kingdom recently launched identity card scheme which has been analyzed by Shaikh and Rabaiotti(2009). They approach the scheme from the perspective of high volume public deployment and describe a trade-off triangle model. They have found that there is a trade-off between several characteristics, i.e., accuracy, privacy and scalability in biometric based identity management system, where emphasis on one undermines the other (Shaikh and Rabaiotti2009). Fingerprint recognition using minutia score matching by Ravi J K.B.Raja, Venugopal K.R. using the minutia score matching method and gives the better FMR value compare to the existing. Fingerprint validation and outlier detection using minutia approach in network security by Devi sirivella, Mrs.D.Raagavamsi gives the better result in real time applications from database type of attacks. Recently Govt. of India started a biometric based ID card i.e., unique identification authority of India ; it provides a unique identity to person residing in India [1].

Fingerprint is used as a biometric template & nominees are used. Gobor and direction filter algorithm is used but it slow in dealing with high capacity requirement. Missed to explain about what failure cause. III. PROPOSED SYSTEM Basically ATMs are networked and connected to a centralized computer, which controls the ATMs. The use of biometric identification is possible at an ATM. Here first all the information of user or client is to be stored at a bank branch or Network Provider at the time of opening the account and then only user can access the ATM. Typical ATM has two input devices (a card reader and keypad) and four output devices (display screen, cash dispenser, receipt printer, and speaker). Invisible to the client is a communications mechanism that links the ATM directly to an ATM host network. The ATM functions much like a PC, it comes with an operating system (usually OS/2) and application software for the user interface and communications. While most ATMs use magnetic strip cards and personal identification numbers (PINs) to identify account holders, other systems may use smart cards with fingerprint validation. The ATM forwards information read from the client s card and the client s request to a host processor, which routes the request to the concerned financial institution. If the cardholder is requesting cash, the host processor signals from the customer s bank account to the host processor s account. Once the funds have been transferred, the ATM receives an approval code authorizing it to dispense cash. This communication, verification, and authorization can be delivered in several ways. Leased line, dial-up or wireless data links may be used to connect to a host system, depending on the cost and reliability of the infrastructure. The host systems can reside at a client s institution or be part of infrastructure. The host systems can reside at a client s institution or be part of an EFT network. The EFT network supports the fingerprint authentication. Point-of-sale services that use biometric solutions are also possible [4]. With the fingerprint reorganization method we also embedded the GSM technique. That the GSM modem connects to microcontroller. That will send the 4 digit code to the user(when the card insert by the main user or nominee the 4digit number only send to the main user only for the knowledge of the main user). After enter the 4digir number the transaction will begin. The user may do the transactions like fund transfer, cash withdrawal, mini statement, bill payment, balance enquiry. After all the transactions done the card will comes out from the machine. In this way by using GSM technology along with fingerprint biometrics we can keep more secure even from the nominee so the if even nominee should not able to do transaction without knowing the main user. Thus we can again avoid the security problems what we face in the previous works [6]. 2014, IJCSMC All Rights Reserved 30

4 A. Functionality of the Architecture This system consists of 3 type of authentication. First it authenticate by the pin number next by the fingerprint and at last it authenticate by the onetime password which is send by GSM modem to the main user mobile number. The functionality of the system will explain by the below steps. Step 1: insert the card Step 2: Enter card s password. Correct password means step-4 follows false means step-3 follows Step 3: The card comes out from the machine and the message send to banker. Authenticated Step 4: choose user type. Main user means step-5 follows. Nominee means Step-10 follows. Step 5: Enroll the finger print. The user finger print already saved in the database. If authentication failure means next step follows. If success means step-7 follows. Step 6: The card comes out from the machine and the message send to banker. Step 7: With the help of GSM four digit one time pass word is send to main user mobile number. Step 8: We need to type the 4 digit one time password on ATM machine Step 9: Then the transaction begins after completion of transaction the card will come out. Step 10: If second type user means the nominee must enroll the finger print then step-7, step-8, step-9 follows. IV. ADVANTAGES OF PROPOSED SYSTEM A. It will provide strong authentication. B. Since many banks are increasing the withdrawal limit from ATMs, the use of a combination of more than one identification technique for high value transactions will reduce fraud and minimize the risk to the banks as well as their customers. C. The nominee user also used so instead of the main user the nominee will access the account in case of emergency. D. People are forced to remember several passwords. Biometric technology does not require the use of a PIN. V. LIMITATIONS A. Due to multiple authentications it is time consuming at initial stage and requires fast and efficient technology to manage such system. B. Biometrics recognition devices are costly, although as the devices become more popular, their cost goes down. VI. CONCLUSION Automatic Teller Machines have become a mature technology which provides financial services to different area and different client in all over the countries. Thus it is very important to make the process more secure and reliable. Thus by implementation of ATM security by using fingerprint recognition and GSM MODEM took advantages of the stability and reliability of fingerprint characteristics. Additional, the system also contains the original verifying methods which were inputting owner's password which is send to client. When this system is fully deployed will definitely reduce the rate of fraudulent activities on the ATM machines such that only the registered owner of a card and nominee, access to the bank account, and the nominee user also will do the transaction so it is more comfortable in case of emergency. Thus the systems become more safe, reliable and easy to use. VII. FUTURE DIRECTIONS A. These are so many fingerprint recognition models are available practice with new fingerprint recognition method. B. Try this with two or more nominees. C. Use the minutia approach for avoiding the database type attacks. 2014, IJCSMC All Rights Reserved 31
